This is how independent energy supply can be quite successful. The screencast shows how easy it is to design a professional island system with Sunny Design Web. 

We guide you through designing an island system and give you tips for your perfect system design. After that, nothing stands in the way of successful operation of the island system.

In this screencast we show you how to set up consumption profiles with Sunny Design Web. You can do it with just a few clicks and continue your system design.

A consumption profile is badly needed when designing an island system or a grid-connected solar system that focus on self-consumption. It describes the daily power consumption and also includes seasonal fluctuations. In grid-connected systems the consumption profile is used to determine self-sufficiency and thus calculates the potential saved energy costs.

Every time when a new generation of the product is launched, people tend to be curious looking for the similarities and differences between the generations. In this blog we’ll look into the differences and improvements of the new Sunny Boy AV-40 compared to the older model, and how it meets the needs of an ever changing market.

The Sunny Boy 3000-5000TL is the world’s most successful residential string inverter, with more than 1 million devices installed worldwide. So when the time came for this trusted platform to be upgraded, the original development team worked hard to deliver a worthy successor.sunnyboy solarinverter old vs new

SMA Quality Worldwide

The Sunny Boy 3000-5000TL was assembled at our facility in Kassel, Germany, while the Sunny Boy AV-40 is assembled at our facility in Yangzhong, China. However, this makes no impact on the final quality the product. The reason lies in SMA Quality systems. Both locations implement the same SMA procedures and systems, which have ensured the quality for SMA devices for over 35 years.

Lighter & Smaller

The Sunny BoyAV-40 was redesigned to provide the same power with fewer components thus increasing product reliability and usability. The circuit boards were also redesigned and stacked to be more space economical, using newer more efficient individual components. All this has contributed to the Sunny Boy AV-40 being 40% lighter and 30% smaller than its predecessor without compromising on quality while at the same time enhancing the features.

Smaller device, smarter screen

The Sunny Boy 3000-5000TL communication was based on a 4-inch LCD screen and Bluetooth connectivity, but times have changed and the Sunny Boy AV-40 has changed along with them. The new inverter is able to communicate with any WiFi-enabled smart device and replaces the old 4-inch LCD screen with a new virtual smart screen improving reliability and access. The Sunny Boy AV-40 gets even smarter when used with an SMA Energy Meter, which can be used to provide consumption data along with its own production information. For information on accessing the inverter Smart Screen, check out our YouTube Tech Tip video.

Quick commissioning with Smart Screen

A major difference between the Sunny Boy 3000-5000TL and Sunny Boy AV-40 is how the inverter is commissioned to meet the local country standards. The Sunny Boy AV-40 is designed to be quickly set up during commissioning via WiFi and its built-in Web User Interface. If an Installer needs to commission multiple devices with the same set of parameters, they can freely use the Configuration File feature which can complete complex programming of an inverter in less than 10 seconds. All this allows for less installation time and lowers costs for all parties.

Smart Connected: the new Standard in Service

The Sunny BoyAV-40 is also the first device in the Sunny Boy family to provide the free Smart Connected Service Package. This helps the Sunny Boys to stay ahead in a modern market where Cloud systems can be used to help work more efficiently and deal with Service issues before you even know there is a problem. And in the unlikely even the inverter needs to be replaced, the Sunny Boy AV-40 will be replaced with a new inverter pre-shipped to the site ready for your installer to replace. This means your system is back up and running at full power sooner, saving you time and money. To learn about Smart Connected, check out this short video or read our blog post here.

A visit home to Australia is always interesting when it comes to climate change reporting in the media, simply because of the controversy around this issue here. Australia has been trying to implement meaningful policy for nearly a decade and has made little progress.

On this visit, my first perusal of a newspaper highlighted the controversy that exists. The Weekend Australian reported on a recent paper in Nature Geoscience that examined the differences in model and satellite measured tropospheric warming rates. The paper focussed particularly on the early 21st century when model warming exceeded observed warming, raising the possibility of a pause in the warming trend.The Weekend Australian opened the article with the words “Climate models were wrong . . . ” and continued with the words “The admission . . . . “, as if there was guilt attached to the finding. This approach sets the tone of the discussion as being negative towards and sceptical of climate science, even though this isn’t the direction being taken by the Nature paper itself. Rather, the paper is about the divergence in model output and observational data presenting an opportunity to better understand the variability of the climate system and therefore improve modelling science.

On a similar note, but at the other end of the spectrum, The Guardian almost gleefully reports a few days after the Weekend Australian that “Hopes . . . . have been dashed by new research.” that longer term warming will be less than expected if based on the temperature rises seen in recent decades. Rather, it explains that longer term warming will be much higher and likely closer to model expectations based on the findings of the paper that they chose to select and discuss.

Both the research papers in question represent different but equally valid attempts by the science community to better understand the underlying climate sensitivity and the reasons for variability. Both papers help advance that understanding and both have proposed reasons why there is divergence between models and observations. This is important work, but the reporting of it leaves much to be desired. 
Picking and choosing particular pieces of work and then amplifying one aspect of those stories with hyperbole isn’t helping inform the public on the reality of the climate issue and the scale of the job in front of society to tackle global emissions. It adds to the divisions that exist rather than attempting to bring the sides together. In both cases, the more informed reporting would have been to tell the reader that the science community is building a better understanding of climate sensitivity and the reasons for variability. But perhaps that’s just a bit too dull for modern reporters!
